The question you're asking is key, and I think we should provide some clarity. Sometimes it's hard to do good. And the bottom line is, the analyst estimates are all over the place. So what we decided to do was to provide a floor. That's by no means guidance in the traditional sense. We're not providing ranges, as Steven noted. It's a floor, number one. Number two is, we do expect the visits to physicians and to dentists to continue to grow. We do expect, therefore, that our consumable business will grow. We'll go back to 2019 levels and grow a little bit above that, too. The same with our specialties and, of course, our software and other value-added services. We do expect Henry Schein’s programs, in general, One Schein, the way in which our sales organization relates to our customers, all of that, to continue to perform well. Having said that, we are in the midst of a pandemic. And so it's hard to provide solid guidance in the sense that we offered in 2019 before -- and before. So we decided to give a floor, which we're pretty comfortable with. Actually, we're quite optimistic about the business. And if we just had a look at 2000 -- in the first quarter, and we had to stop things now, I would say we're very optimistic. Having said that, we can't tell where this pandemic is going to hit. No one can tell. And just like a year ago, we cautioned investors about the pandemic. We're doing the same now, although we're a little bit more confident today than we were in February and March of 2020. What we're saying is we're comfortable with the bottom -- with the floor of the guidance we've given. We just can't give ranges. And yes, we believe our consumable business, our equipment business, our software business, our specialty businesses, are all poised to do well. And if the music stopped today, we think we'd have a very good 2021. But again, we can't tell where this is heading. I must say, though, that as one goes to the east and then comes west, things are getting better. Our Asia businesses are pretty much back to normal, doing quite well, Asia Pacific. Europe is okay, except for the U.K., where, hopefully, the reimbursement of dentists will encourage reimbursement for dentists to see more patients again. And in the U.S., it's pretty stable, both in dental and medical and we're hopeful that the 80% will start going back to normal to the pre -- to the 2019 levels as the year goes by. But exactly in which quarter, it's very hard to tell. All I can say is we are and we continue to be very optimistic about our business and are very pleased with the performance so far this year.
